that bottem button is the best... and with David's precision it glides so smoothly and easy to push that even your pinky finger will have no problem pushing it..... 18.5mm is the width... length well you have to ask David for that one.Geez... more temptations. These devices are so slim and pleasing to the eye alright, and definitely built to last. That 16340 batt size hits the spot for me, a good balance between physical size and charge capacity. Not sure about the bottom button thing for me personally?
I'd really like to know the height as well as the width?
